Active Optical Cable Vs Transceiver

This blog is part 2 in a 3 part series on mellanox s high speed interconnect products.

Active optical cable vs transceiver.

Since the passive dac cable contains no active components it provides a direct electrical connection between corresponding cable ends. 10gtek s sfp active optical cable transmits 10gbps data in each direction over. 10gtek s sfp active optical cables are hot swappable low voltage cable assemblies that connect directly into sfp modules at both ends. It uses electrical to optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.

As one kind of optical transceiver assembly a direct attach cable dac is used to connect one mobility access switch with another when forming a stack which can be either passive or active. Optical transceivers active optical cable and direct attach twinax cable solutions mpo mtp solutions sas solutions stacking cables fiber optic patch cords plc splitters multiplexers demultiplexers as well as other data center and cloud solutions. My first blog covered direct attach copper dac cables which are the least expensive way to create a high speed 25g 50g 100gb s interconnect but have a maximum reach of about 3 5 meters. Active optical cables enable efficient system airflow and have no emi issues which is critical in high density racks.

Transceivers transponders and active optical cables sfp copper and optical. We offer a wide range of transceivers and cables in a variety of form factors including. What s the difference between active and passive direct attach cables dac. Hpc optics is a trusted supplier of fiber optic transceivers active cables and interconnects for data centers and high performance networks.

The blueoptics and bluelan brands include the following products. So the basic idea of aoc is to embed the active optical transceiver components into the electronic connector instead of using separate optical transceiver and pluggable fiber cable. Active optical cable aoc can be defined as an optical fiber jumper cable terminated with optical transceivers on both ends. These cables use a 20 position connector with active circuitry to increase distances and to improve emi and reduce signal loss.

Cbo is a manufacture of active and passive network solutions. Sfp gbic sfp xfp qsfp qsfp28 cfp twinax direct attach cables and active optical cables. This active optical cable is electrically compliant with the sfp interface and supports infiniband ethernet fibre channel myrinet and other protocols. Back in the past when internet speeds were never more than 10 gbps networking equipment consisted of many sfp transceiver plug in slots and a lot of rj45 ports that had the capacity to run at 10 100 1000mbps.

Longwave shortwave and wdm datacom applications using fast ethernet gigabit ethernet 1x 2x 4x fibre channel telecom applications using oc 3 stm 1 oc 12 stm 4 oc 48 stm 16 epon gpon and wireless cpri across all reaches. Active optical cables are much thinner and lighter than copper cables which makes cabling easier. Active optical cable aoc wiki. Cisco currently offers active optical cables in lengths of 1 2 3 5 7 10 15 20 25 and 30 meters.
